Filed: 1965-10-13
Abstract: 1,092,490. Telegraphy. SIEMENS A.G. Oct. 13, 1965 [Oct. 14, 1964; Aug. 4, 1965], No. 43362/65. Heading H4P. A teleprinter system has means whereby input of data to a receiving printer is stopped on reception of certain function signals and resumed when the function has been performed. In one embodiment, when a carriage-return signal is generated at the transmitter keyboard, the keyboard is held inoperative and CR signals are automatically repeated until the carriage of the local printer has returned to rest. A punched tape record may be made, and data from a punched tape can be used as input data. In a second embodiment employing teleprinters operating at different speeds, a counter determines the length of each line of data stored in a buffer store and inserts pauses following the CR signal, the number depending upon the length of the line and being sufficient to ensure completion of the CR operation before the next line of data is read out of the buffer.

Title: Improvements in or relating to electrically controlled driving apparatus
Inventor: HARRISON HENRY MILBURN
IPC: G11B15/48
Filed: 1959-12-30
Abstract: 934,174. Change-speed control. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 7, 1960 [Dec. 30, 1959], No. 44170/59. Class 80 (2). An electrically controlled driving apparatus comprises means for driving a rotatable member in the forward or reverse direction, a brake for decelerating the member, means for generating an electrical signal when the speed of the member falls to or below a predetermined value, control means for removing the forward drive and applying the brake to initiate reversal, and means responsive to the signal to remove the brake and reverse the drive. The invention may be applied to the drive for one of a pair of computer spools regulating the passage of magnetic tape to and from an associated storage bin, the system shown comprising electric motor-driven magnetic powder clutches 4, 6 for rotating the spool in the forward and reverse directions, a magnetic powder brake 5 and associated memory control unit 1, memory unit 2 and spool control unit 3. Unit 1 comprises an " AND " gate 7 with inputs from a spool-driven tachometer and the brake 5; unit comprises two AND gates 10, 11 and two " OR " gates 12, 13, one input of gate 12 receiving the command signals; unit 3 comprises two AND gates 16, 17 and an OR gate 18 controlling the clutches 4, 6 and brake 5 respectively, the output from the bin sensing apparatus being fed to the trigger circuit 15 of gate 17. The tachometer supplies positive (1) signals when the spool is stationary and negative (0) signals when it is rotating, and the arrangement is such that command signals fed to gate 12 are only effective to energize clutch 4 or 6 when the bin sensing signal indicates that the bin has completed a previously initiated filling or emptying operation. Thus, 0 command signals fed to gate 12 to condition clutch 6 only make the drive effective when a 0 bin sensing signal fed to circuit 15 indicates that the bin is empty and requires filling, since under these conditions if the brake 5 is applied and the spool is stopped they each feed a 1 signal to gate 7, and a 0 bin signal feeds a 0 signal to gate 17 and a 1 signal to gate 16, the latter passing a 1 signal to clutch 6. Simultaneously, gate 18 receives a 1 signal from gate 16 and a 0 signal from gate 17 and passes a 1 signal to circuit 9 so that a 0 signal is fed to brake 5 to release the latter and allow the spool to be driven. Similarly, a 1 command signal fed to gate 12 conditions clutch 4 to drive the spool in the reverse direction when a 1 bin signal fed to circuit 15 indicates that the bin is full and requires emptying. Specifications 930,554 and 934,173 are referred to.

Abstract: 1,090,301. Polarizing image-animators. VISORAMA PRINTED MOTIONS CO. Oct. 30, 1964, No.44326/64. Heading G2J. [Also in Division G5] In a display device in which light from sources 21, Fig. 1, is polarized by a rotating polarizer 22 and then passes through a fixed analyzer 27 so that travelling shadows appear to pass over a transparency 24, a light intercepting sheet 26, is arranged in the light path and is embossed or otherwise provided with ridges and depressions 25 forming a series of lines which are so arranged that various types of motion appear to take place on the transparency 24. In an example, Fig. 2, in which the transparency 24, which may be any transparent or translucent sheet material such as glass, plastic or paper, has a picture of a gear-wheel 24' and rack 24" thereon the analyzer 27 is so cut and positioned behind the transparency 24 as to overlie only the portions depicting the gear-wheel and rack so that there is no shadow movement over other parts of the transparency and the sheet 26 positioned behind the analyzer has a plurality of concentric rings 25 embossed thereon corresponding with the gear-wheel 24' and a pattern of lines at progressively varying angles embossed thereon to correspond with the rack 24". When the polarizer 22 is rotated by electric motor 23, therefore, the wheel 24' appears to rotate and rack 24" appears to move linearly. The Specification refers to many different patterns which can be embossed to provide different forms of apparent motion such as random, reciprocating, radially inward or outward or hesitating rotary motion. The desired patterns may be drawn and photographed and the photographic negative employed in a photoengraving process to produce an embossing plate for embossing large numbers of intercepting sheets 26. Alternatively the sheets 26 may be produced by a raised printing process after which a metal coating is depositied on the raised lines. Either the polarizer or analyzer may be rotated and several of the elements e. g. light intercepting sheet 26, analyzer 27 and transparency 24 may be bonded together by adhesive. Such a three-ply lamination in the form of a small slide may be inserted in a projector which has a rotary polarizer for projecting the picture on a wall or screen. The polarizer or analyzer may be formed from a sheet of polyvinyl alcohol coated with polarizing ink. In another form since reflected light is partly polarized, the picture is painted on a reflecting surface and the latter acts either as polarizer or analyzer e.g. a floodlight having a rotary polarizer in front of it may be positioned on the ground to illuminate a bill board having a reflecting surface which acts as the analyzer.

Abstract: 945,116. Fluid actuation of switches. WARD & GOLDSTONE Ltd. Dec. 28, 1961 [Dec. 28, 1960], No. 44400/60. Heading H2B. The Specification describes the switch of Specification 945,117, but the claims relate to the snap-action switch mechanism. A movable contact-carrying blade 9 is riveted to a support and has a central actuating tongue 11 which rests for a large part of its length on a boss'8. This supporting boss 8 is at a higher level than the upper contact 26 of the two stationary switch contacts 26, 27, and the movable switch contact 25 would thus tend to engage the upper contact 26 if rocker spring 28 connecting tongue 11 with the movable contact-carrying blade 9 were absent. The fluid pressure values at which the switch will operate are adjustable by raising or lowering the stationary contacts relatively to boss 8 using screws 42, 45. A coarse adjustment is possible in the height of the support for the actuating tongue 11 by allowing it to bear on an insulating plunger 48 in the boss 8, the position of such plunger being adjustable by a screw 49.
